0–100, higher is better. How it is calculated

The website zoskolydoskoly.sk is an e-commerce platform specializing in children's books targeted at children aged 0 to 12 years. It offers a wide catalog of books with a focus on educational and entertaining literature for young readers. The site is localized in Slovak language and hosted on a Slovak hosting provider, indicating a regional focus. The business appears to be newly established in 2024, consistent with the domain registration date. Technically, the website uses standard web technologies including HTML5, CSS, JavaScript, and integrates Google Tag Manager for analytics and tracking, although it currently denies ad and analytics storage by default, showing some privacy consideration. Security posture is moderate with HTTPS and DNSSEC enabled, but lacks security headers and formal security policies. No privacy or cookie policies were found, which is a compliance gap. Contact information is not explicitly provided on the visible content, which may affect user trust and support accessibility. Overall, the website is professionally designed with good navigation and content relevance, suitable for its target audience. The content is safe with no adult or explicit material.

This scan rated NIS2 with an earlier keyword method that is no longer shown; rescan for the per-article view. Risk management, continuity, supply chain, training, MFA, management oversight (Art. 20) and incident reporting (Art. 23) need internal evidence, and Guard cannot tell whether NIS2 applies to this organisation.

GDPR is indicative only, based on publicly visible signals: Articles 7, 12, 13 and 32 of Regulation (EU) 2016/679 and Article 5(3) of the ePrivacy Directive. Not a certification or legal assessment.

Priority findings

9 findings rated critical or high. Fix these first.

  1. GDPR outside view

    These are the privacy signals visitors and data protection authorities look for under GDPR.

    • Critical

      EU business without adequate privacy measures

      EU businesses are subject to strict GDPR requirements

      What to do: Implement comprehensive GDPR compliance including privacy policy, cookie consent, and data protection measures

    • High

      No Privacy Policy found

      GDPR requires a clear and accessible privacy policy

      What to do: Add a comprehensive privacy policy page and link to it prominently

  2. Security headers

Results by check

Each check with its score, findings and the evidence it collected.

How this score is calculated

The security score runs 0–100, higher is better. It is the plain average of the security checks that completed in this scan, each counted equally. A check that could not run is left out: it counts neither as a pass nor as a fail.

Not counted

  • NIS2 outside view: Re-weights evidence from the TLS, email, DNS, network and hygiene checks, so counting it would count that evidence twice. Shown on its own.
  • OffSeq Observations: An AI reading of the site, useful context but not reproducible evidence. Shown on its own.

Findings that cap the score at 49

Each of these is serious on its own, so while any is present the site cannot rate better than high risk, however good the other checks are.

  • The certificate is not trusted by browsers
  • The website is not served over HTTPS
  • A database, remote desktop, file-sharing or Telnet service is reachable from the internet
  • The page loads a script from a compromised source
  • The domain registration has expired
  • SPF authorises every server to send mail as the domain

Partial scans

When the site blocks Guard or most checks cannot run, the score covers only the checks that ran (usually DNS and email), is capped at 75 and is shown as partial, without a risk level.

Technical appendix

Business context, site observations and technical notes gathered during the scan, and the standards behind each reference.

Business context

Business profile

The business operates in the education and retail sectors, focusing on children's literature. Its business model is direct online sales of books, likely generating revenue through e-commerce transactions. The market position is niche, targeting Slovak-speaking families and educational institutions. The extensive catalog suggests a broad offering within its niche. The company is small-sized and newly founded, with no visible parent or subsidiary companies. The lack of visible contact details and policies may limit customer confidence and regulatory compliance. The use of Google Tag Manager indicates some marketing and analytics efforts, but the absence of cookie consent mechanisms suggests room for improvement in privacy compliance. There are no detected partnerships or related domains from the data provided.

Security posture

The website benefits from HTTPS encryption and DNSSEC, which are positive security indicators. However, the absence of security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options reduces the defense-in-depth posture. No incident response or security policy pages are present, and no vulnerability disclosure or security.txt files were found. The site uses third-party scripts like Google Tag Manager, which should be regularly audited for security. No exposed sensitive data or vulnerabilities were detected in the provided content. The security score is moderate, but improvements are needed to enhance protection and compliance, especially regarding privacy policies and security headers.

Recommendations

  1. Implement and publish a comprehensive privacy policy and cookie policy to comply with GDPR and enhance user trust.
  2. Add security headers such as Content-Security-Policy, X-Frame-Options, and X-Content-Type-Options to improve security posture.
  3. Provide clear contact information including company email and phone number to improve business credibility and customer support.
  4. Develop and publish a security policy and incident response contact details to demonstrate security maturity.
  5. Regularly review and audit third-party scripts and tracking tools to minimize security risks and ensure privacy compliance.

Technical notes

Notes

The website uses a standard technology stack with HTML5, CSS, JavaScript, and Font Awesome for icons. Google Tag Manager is integrated for analytics and tracking, with consent set to deny ad and analytics storage by default, indicating some privacy awareness. The hosting provider is websupport.sk, a Slovak hosting service, and DNSSEC is enabled, enhancing DNS security. The site appears mobile-optimized with responsive meta tags and viewport settings. Performance is moderate based on the use of multiple images and scripts, but no explicit performance metrics were provided. The site lacks advanced frameworks or CMS indications, suggesting a custom or lightweight platform. SEO is basic with meta description present but no keywords or Open Graph tags detected. Accessibility features are minimal but basic navigation and form elements are present. Overall, the technical implementation is solid but could benefit from modernization and enhanced security features.
Standards and sources

Reference chips under each finding point to the standard, regulation or specification the finding relates to. They are taken from the official datasets below and mapped conservatively: a finding with no defensible link shows none. NIS2 and GDPR references mark where a finding is relevant evidence, not a compliance verdict. Implementing Regulation (EU) 2024/2690 binds digital infrastructure and digital service providers; for other entities it is the most detailed public reading of the Article 21 measures. WCAG, EN 301 549, European Accessibility Act and Web Accessibility Directive references name the requirement an automated accessibility rule relates to; they are not a conformance verdict.
